I just bough 2 bag of this stuff.
Can someone tell me what's the stuff in the pic is?
Will it be safe with bottom feeder?
It is breakable and just wanna make sure its safe since one did poke into my skin
Every bag has those in there or is t just my?

Out of the 200lbs I got I never came across anything like that.

I just bought 50lbs a few days ago and I have the same stuff in mine. I've read other threads where people found this and went with BD anyhow without problems. I'm just hoping that I don't run into any real issues with the stuff.

I'm keeping bottom feeder like cory, my black ghost knife, and bumble bee cat.
Since cory like to dig I wonder if it will be safe. Just don't want to wake up seeing a piece stuck on one of my fish.

I wouldn't worry about it. If anything just rinse it well to make sure you don't get any shavings. I'm using some in my 10g shrimp tank and love the stuff.

I also just got a bag of black diamond and it has these too. They appear to be the same material as the "grains" just shaped differently.

I think it's just glass shards. Mine has it too. No ill effects in my shrimp tank thus far but I am guessing shrimp aren't really as susceptible to substrate texture like bottom feeder fish.

Be sure to report back with how it goes. I'm confident that you'll have no problems!

It is just the same stuff as the media, not broken up.

I didn't have any in mine but just use a some type of metal screen. We used it to was before putting into the tank. Really helped with water clarity from the beginning.

I will report in how it goes.

For now here my sand washer. Hehe
5 gallon bucket from Lowes cut about 4-5 inch from the bottom.
Cover with one of my t shirt haha. Work like a pro no sand can go through it.

Put sand.in there and hose it down till water look clear.
Rule 1 is wash couple cup by cup.

You might try using a magnet to see if any of those pieces have steel in them. At least some of them look metallic. I would do that before the sand gets wet.
